Zero Cross Turn-On and Random Turn-On Models Available
Both zero cross turn-on and random turn-on models are available, enabling stable operation under various load conditions.
-
Zero Cross Turn-On
The relay switches ON/OFF when the voltage reaches the zero-crossing point, minimizing inrush current and noise. This control method is ideal for resistive loads such as heaters and lamps, ensuring smooth and stable operation.
-
Random Turn-On
The relay switches on immediately when the control signal is applied, providing a fast response when required. This control method is ideal for motors and inductive loads, and offers flexible control for various power control methods, including phase control.
Applications
Machine tools industry, SMT machine, Solid state relays used for temperature control of SMT machinery.
